Application fllcd May .3, 1906. Serial Nn. 314.948-

To. all whom t mayfconcern.- Be it' known that I, HENRYD. HIBBARD, a citizen Aof the United States, residing in APlainfield, inthe county of Union and State of'New Jersey, have invented certainnew and useful Improvements in-Vaults, of which the following isaspecifioation.

This inventionv relates to burglar or mob proof vaults, .and particularly to `that vstructure of vault which, owing-to its'size, is neces-1 sarily made up of la number of members or plates fastened or connected together andit more particular-ly relates to that part thereof known and usually designated as the vestibule of thevault, the object ofl the inventionlbeing to provideanlimproved vestibule member or castingso formed that it will afford great rigidity andstiffness to that part ofthe vault. in which the doorway or entrance-passage isforrned and prevent the sagging thereof, andthis-without the necessity of increas'ingthe thickness ofthe metal of the plate or casting in which such doorway is formed.y

A further object is thev provisionof animprovedvestibulemember or plate formed as an integral .structure and in Isuch manner that all longitu'dinaljoints are located away from the corners-of the casting-so that no fastening meansl are requiredtooonnect the vestibulemember to the frontA plate ory casting of the'vault.

A further objectief the invention is the provision` of anl improved structure which will enable the use of avestibule, andtherefore of a door, of materially less area than that of the front of the vault. without requiring the use of fastening ',meanswbetweenthe vestibule portionland the `front plate or memberof the vault.

In the drawingsaccompanying and forming-A apart ofthis speciiication, Figure 1 is a perspective view of one form of thisimproved vestibule member orf plate, this form being particularly well adapted for use witha rectangular door. Fig. `2Y is a perspectiveview of anotherv form of this improved vestibule late or member, this form being particuarly welll adapted for use with a circular door. Fig. 3 is -azperspective view of. another form of improved. vestibule members or plates,.this view showing. a pair thereof assembled. Fig. 4 is across-sectional view of a vault vwith that forrnfof this improved vestibule member orplate shown in Fig. 1 inlitsY proper position; and Fig. 5 is alsoa sectional view of a vault with that 4form of vestibule member` or platev shown in Fig. 3 assembled inits proper position.

Similar characters of reference-v indicate corresponding parts throughoutthe different iigures of the drawings.`

Vaults of large size are necessarily made up of a number of plates, members, or castings suitably connected'or fastened togetheredgewise, and such vaults require and are furnished with doors of sufficient sizeto enable them to be readily entered bythe users thereof, inconsequence of which it has been .found that that particular member or casting in which the doorway is formed has a tendency to sag,vowing tothe fact thatwhen the castingf is made-with a large part of themetal necessarily removed to form the doorway there is-insuflicient metal left around such doorway to Y'give stifness and rigidity to the casting suflicient to prevent it from sagging, the remaining part of the metal in suchl-plate being insufficient -to support orretain-such a large casting in its-normal shape, and this sagging has taken place to such an. extent that the door when circular becomes out of round, in other words, does not fit true in its jamb, requiring considerable effort to close it and also adjustment ofthe door at various times-,to insure the closingthereof ina-proper manner.. This sagging is also assistedto a large extent by the weight of the roof of the vault, and as itis impracticable andundesirable and at times impossible to increase the thickness of this particular casting of the vault to-any great or appreciable extent beyond'the thickness of the other castings making up the body it follows that when the plate or casting'is formed witha large doorway or opening therein it must be stiifened in some practicable manner without' increasing the thickness `of the metal, which in aimanganesesteel vault is -usually only about three inches thick.

ln those structures where the doorway. is

TOO

of substantially the same size as the body of i.

which, asstated, is integral with the-body, is of ample strength and stiffness; but where it is necessary, as in the building of large vaults, to construct them of several members or castings and where the door must necessarily be of less size than the front of the vault it is essential that that particular casting in which the doorway is formed shall be of great rigidity and strength for .the reasons hereinbefore stated. It is also frequently desirable in order to decrease the number of joints, and thereby the number of fastenings, to form the front or the front member of the vault of as large a casting as possible; butit -is not practicable nor necessary nor desirable tor-.provide a doorway, and therefore a door, of the same size, so that it becomes a material object and advantage to rovide a structure in which the door may e considerably smaller than the front or front plate of the vault and yet be sufficiently large to enable entrance of one or more persons to the vault and todo this by the formation of a vestibule, which is frequently required, without, however, the use of fastening means where such vestibule is joined to thefront or front member of the vault. Y

.The object of the present invention, therefore, is the provision of a structure which will enable-the formation of a vestibule of considerable size to permit proper entrance to the vault, but of materially less size than the Y front plate or front of the vault, without the necessity of using fastening means at the point where the vestibule is joined to the front member or front of such vault, while also so stiflening and reinforcing that casting having the doorway that it is not weakened', and therefore will not sag when in use. This improved vestibule member or casting A, which I have herein designated as the vestibule-forming lmember, comprises in its preferred form a forwardly-extending plate or flange .2, forming a part of the vestibule and having integrally formed therewith a transversely-extending plate or flange 3, forming to the extent thereof the front wall ofthe vault, which in turn is usually, and is shown in the drawings, provided with one or more rearwardly-extending plates or flanges 4, constituting to the extent thereof a part of the side or top walls of the vault. j

In the form shown in Fig. 1 the vestibule member comprises a forwardly-extending plate or flange 2, a rearwardly-extending plate or flange 4, integrally united by a plate 3, extending transversely of said flanges. In this form it will be observed that the rearwardly-extending flange 4 extends entirely around the outer edge of the plate 3, while the forwardly-extending flange 2 extends entirely around the doorway or inner edge of said late 3, each of such flanges being provided) adjacent its free edges with suitable means for the reception of fastening devices,

(shown in the present instance as a lseries of projections for the reception of linl -bolts,) which may be secured thereon in any suitable manner-as, for instance, by being shrunk thereon.

In the form'of vestibule member shown in Fig. 2 the plate 3 is provided with a rearwardly-extending flange 4 only at two sides, (shown as the top and bottom thereof,) the plate 3 beingprovided in this instance along its two free edges with means-such, for instance, as projections-for the reception of fastening devices.

In the form shown in Fig. 3 the vestibule structure is made up of a pair of members or castings, in each of which the plate 3 is provided with but one rearwardly-extending flange 4, while the forwardly-extending flange 2 is a three-sided one only, the two members being fastened midwayof the height of the vestibule by suitable fastening means, preferably similar to those liereinbefore described. It will be noted, however, that even in this form there is no fastening means needed or required longitudinally of the corners between the forwardly-extending flange or vestibule portion 2 of the structure and the plate 3 of the casting, where it would be extremely difficult to obtain a sufficiently strong, accurate, and tight-fitting joint. As such joint also facilitates the lodginent of explosive material and increases the effect thereof, it is essential that it be so formed as to have superior resisting qualities.

In the vault shown in Fig. 4 the vestibule member illustrated in Fig. 1 is assembled, from which it will be seen that in front thereof is located the door-frame 5, supporting tlie door, and in the rear thereof the other members 6 of the vault, which are used to make up the vault-body. In the formsshown in Figs. 1 and 3 the vestibule members are particularly constructed for use with a rectan gular door, while in the form shown in Fig. 2 the vestibule member .is particularly constructed for use with a circular door, the manner of assembling the form of castings shown in Fig. 3 in connection with the vaultlhoody and the door-frame being shown in In some constructions of vaults it may be desirable to extend the transversely-extending plate 3 above or below, or both above and below, the forwardly-extending flange 2 in the saine manner as this plate is shown, extended at the sides beyond the flange 2 in Fig. 2, and with or without the rearwardlyextending flange 4, and the same advantages to a large extent are obtained should the castings be made in quarter-sections instead of half-sections, as in Fig. 3, all of which is within the purview of my invention.

By constructing the vestibule-forming member in the manner shown it will be apparent that the forwardlyextending and IOO IIO

ISO

also the rearwardly-extending flanges materially stiffen and reinforce the plate 3, which forms one of the lfront walls of the vault, so that even with a large door opening therein the metal of this plate around said doorway is materially strengthened and reinforced so that it will not sag, and this without the formation of joints at the corners, where the flanges are'joined to the plate, thus doing away with the necessity of using fastening devices at these points, which, as stated, 1s `very undesirable. Thus by angling the front plate in the manner set forth not only is an integral structure provided without any joints between thevestibule-forming flange and the front plate of the vault or between such plate and the rearwardly-extending flange when this is provided, but one in which without the use of fastening means for connecting the several components thereof together the front or front plate of the vaultmay be made of a relatively large casting while enabling the vestibule to be made of smaller dimensions but of sufhcient size to give proper entrance to the vault. Each edge of the plate where in connection with a companion plate a joint is'formed is provided with a swell or bead 7, which not only reinforces the edge of the plate by reason of the increased amount of metal at this point, but also reinforces it in other ways-for instance, it facilitates the heat treatment of the casting when it is desired to develop superior properties in the steel by heat treatment, and especially if they are made of manganese steel-that 1s, of steel having a predetermined quantity of manganesethere- I claim as my invention- 1.
